Abstract

The invention discloses a vehicle distance control system based on communication among vehicles and a control method thereof. According to one aspect of the invention, the vehicle distance control system based on communication among vehicles comprises a relative distance and speed input part which receives a relative distance and a relative speed between a front vehicle and the vehicle; a communication part which receives pavement information from an identified front vehicle; a constant changing part which compares the received pavement information with the pavement information received at a previous time point and changes a vehicle distance constant when the pavement information changes; a target vehicle distance calculation part which calculates a target vehicle distance between an identified front vehicle and the vehicle according to the changed vehicle distance constant; and a target acceleration calculation part which utilizes the received pavement information to calculate a target acceleration of the vehicle. According to the invention, a safe distance is ensured according to pavement assistance.

Description

technical field [0001] The present invention relates to a vehicle-to-vehicle communication-based vehicle distance control system and a control method thereof, in particular to calculating the road-based target vehicle distance of a vehicle traveling behind by using road surface information received from a vehicle traveling ahead through vehicle-to-vehicle (V2V) communication A vehicle-to-vehicle distance control system based on inter-vehicle communication and a target acceleration and a control method thereof. Background technique [0002] According to statistical results, with the rapid popularization of vehicles, the growth rate of vehicles is much faster than the expansion speed of road network. [0003] Therefore, with the increasing risk of collisions between vehicles on the road, in combination with consumer demand for safer and smarter cars and the development trend of the car-related industry, various smart safety systems have been developed and put into use .
